BALING-IPRESS.

Specification of letters Patent.

Patented Nov. 9, 1909.

Application filed. April 25, 1908. Serial No. 429,236.

To all whom it may concern:

Be it known that I, FRED A. BOTHWELL, of East Genoa in the county ofCayuga, in the State of New York, have invented new and usefulImprovements in Baling- Presses, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to certain improvements in baling presses and isparticularly adapted for balinghay, straw and similar material.

My main object is to form the bales contion of suitable followersbetween the pis-.

ton and previously compressed portion of the hay as each bale is formed.i

A further object is to provide means for reciprocating the piston atregular prede-,

termined intervals across the inletopening for the loose hay whichis'forced into the press when the piston is drawn backward and iscompressed in the tapering portion of the press at the opposite side ofthe inlet by the advance stroke of the piston.

Other objects and uses relating to specific parts of the machine will bebrought out in the following description. s

.In the drawingsFigure 1 is a longitudinal vertical sectional view of abaling press embodying the various'features of my invention. Fig. 2 is ahorizontal-sectional view taken on line 2-2, Fig. 1. Figs. 3 and 4 arevertical sectional views'taken'on lines 33, and M, Fig. 1.

This press comprises essentially a rectangular box or frame 1 disposedin a horizontal position and open at its-front and rear ends andprovided with an inlet +2- in its top near the front end. This box orframe 1- is preferably of greater vertical height than the transversewidth to enable the bales to be formed on end and the portion thereof atthe rear of the inlet -2 tapers rearwardly thus forming a taperingdischarge opening into which the hay is compressed and formed into baleswhich are successively discharged from the tapering outlet under thecontinued action of the reciprocatory piston 3. This piston fits closelyand is movable within the front end of the press box or frame -1 acrossthe inlet opening 2 through which the loose hay is fed when the pistonis at its extreme backward stroke as shown in Fig. 1, the lower edgeiofthe piston being provided with suitable anti-friction rollers -l whichride upon the bed or bottom -5 of the box, the portion of said bottom 5directly under the inlet -2 being provided with apertures 6 throughwhich the dust, chaff and other fine foreign matter may readily sift.

The piston -3 is connected by suitable forwardly extending braces 7 to asliding cross head 8 which is guided in suitable ways -9 at the front ofthe press box or frame, said cross head being connected by a pitman orrod l0 to an eccentric 11, the latter being secured upon a suitabledriving shaft 12 as best seen in Fig. l.

I preferably provide opposite sets of ways 9' located at opposite sidesof the cross head 8 for receiving anti-friction rollers 13, which carrythe cross head. This cross head and connecting rod are substantiallycoaxial with the central axis of the press box or frame 1- as best shownin Figs. 1 and 2, the connecting rod 10- being eccentrically pivoted toand between opposite pairs of gears lt, the latter being adapted to beconnected to any available source of power, not necessary to hereinillustrate or describe. These gears or eccentric driving elements l4 aremounted upon suitable forward extensions 16- of the press box frame 1some distance in front of the guides 9- for the cross head, andtherefore, a greater distance in front of the piston head 3-, the objectof which is to obtain a considerable throw of the piston at each stroke.

Movable in the opposite sides of the press box or frame 1 are pivotedpawls or detents 18- which are normally pressed inwardly by suitablesprings 19, the detents being located just at the rear of the inlet 2'and preferably in planes one above the other from the top to the bottomof the box as best seen in Fig. 4. The object of these detents is toretain the compressed hay in its advanced position as compressed by eachforward stroke of the piston 3 Therear ends of the bottom and top of thebox as previously stated taper toward each other and the rear ends ofthe opposite sides which are usually made of open slat work are alsotapered toward each other as best seen in Fig. 2 thereby producing thetapering outlet previously mentioned.

The loose hay is inserted by any suitable means through the inlet 2 inthe top of the press box in front of the retracted plunger -3- andduring the advance of the plunger, this loose hay is gradually compressed in the tapering end of the box at the rear of the inlet, a freshquantity of hay being inserted at each recession of the piston and asthe piston forces this loose hay rearwardly, it compresses such hayhorizontally while the tapering top, bottom, and sides of the box exerta compression force upon the hay vertically tending to retard itsrearward movement until a sufficient quantity has been pressed to form abale, such quantity being determined by the position of the advance endof the compressed hay within the tapering outlet and this position isusually indicated on the box by a mark 20 or other indicating device asbest seen in Fig. 2, the forward limit of the stroke of the piston 3determining the position of the other side of the bale.

After each bale is formed in the manner just described, a suitablefollower -21 is inserted between it and the plunger usually through theside of the box or the inlet opening 2- as may be desired, such followerbeing forced by the piston 3 against the adjacent side of the bale. Assoon as this follower is placed in position behind the bale, additionalloose hay is placed in the box in advance of the retracted piston -3whereupon the loose hay as it is fed into the press box is pressed bythe successive strokes of the piston 3 against the follower -21 therebyadvancing the first formed bale through the tapering outlet until theadvance end of the pressed hay for the second bale reaches the indicator20 thus forming a second bale, this operation being repeated after theformation of each new bale and as these bales accumulate in the taperingend of the box they are bound by suitable tic wires 22 as best seen inFig. 1 in which the followers are shown as provided with transversegrooves 23 through which the wires are threaded and tied horizontallyaround the bale at intervals from top to bottom using as many tie wiresas may be necessary to secure the hay in the bale.

During the continued operation of forming the bales they aresuccessively discharged under the pressure of the piston 3 so that theoperation of forming the bales is practically continuous.

The resistance of the tapering end of the press box to the advance ofthe compressed hay taken in connection with the stroke of the piston andindicator as 20- is such as to determine approximately the weight aswell as the size of the bale which may be compressed between the advancestroke of the piston and indicator -20 so that each bale is ofpractically the same size and weight.

It will be seen from the foregoing description that by forming the balewith its greatest length vertically and binding the tie wires around ithorizontally, the work of binding is much easier and more expeditiousand in addition to this the hay stalks are left more uniformly theirnatural length instead of being broken up as is usually the case whenthe bales are pressed endwise or horizontally, that is the stalkspassing through the inlet opening in the top assume a more nearlyvertical position and in this position are pressed into the bale.

What I claim is:

In a hay press, a rectangular horizontal press box open at both ends andhaving its top formed with an inlet for the hay, the baling chamber ofsaid box tapering from the said inlet to the discharge end of the box, asupporting frame for the press box extending forwardly beyond the inletend, a recip rocatory piston movable in the forward end of the boxacross the inlet, a sliding cross head connected to the piston, guidesfor said cross head secured to said frame, a revolving eccentric mountedin the forwardly-extending portion of the supporting frame, and aconnecting rod between the eccentric and cross head for reciprocatingthe piston.

In witness whereof I have hereunto set my hand this 20th day of April1908.
